Evidence for reduced collectivity around the neutron mid-shell in the stable even-mass Sn isotopes from new lifetime measurements
Precise measurements of the lifetimes of the first excited 2(+) states in the stable even-A Sn isotopes Sn112-124 have been performed using the Doppler shift attenuation technique. For the isotopes Sn-112, Sn-114 and Sn-116 the E2 transition strengths deduced from the measured lifetimes are in disagreement with the previously reported values and indicate a shallow minimum at N = 66. The observed d

Polarized neutron powder diffraction studies of antiferromagnetic order in bulk and nanoparticle NiO
In many materials it remains a challenge to reveal the nature of magnetic correlations, including antiferromagnetism and spin disorder. Revealing the spin structure in magnetic nanoparticles is further complicated by the large incoherent neutron scattering cross section from water adsorbed at the particle surfaces and by the broadening of diffraction peaks due to the finite crystallite size.

A stand-alone tree demography and landscape structure module for Earth system models
We propose and demonstrate a new approach for the simulation of woody ecosystem stand dynamics, demography, and disturbance-mediated heterogeneity suitable for continental to global applications and designed for coupling to the terrestrial ecosystem component of any earth system model. The approach is encoded in a model called Populations-Order-Physiology (POP). We demonstrate the behavior and per
Mapping the mechanics and macromolecular organization of hyaluronan-rich cell coats
The hyaluronan (HA)-rich pericellular coat (PCC) enveloping most mammalian cells plays a vital role in biological processes such as cell adhesion, proliferation, motility and embryogenesis. In particular its presence on chondrocytes, which live in the load-bearing cartilage, has a wide range of implications in diseases such as osteoarthritis, highlighting its mechanical role in living organisms. D
Alpha-ketoglutarate protects the liver of piglets exposed during prenatal life to chronic excess of dexamethasone from metabolic and structural changes
Glucocorticoids play a role in the origin of the features of the metabolic diseases. Alpha-ketoglutarate (AKG) is defined as glutamine homologue and derivative, conditionally an essential amino acid. In the liver, glutamine serves as a precursor for ureagenesis, gluconeogenesis and acute phase protein synthesis The aim of the study was to determine the effect of AKG administered to piglets prenata
Low sex hormone-binding globulin is associated with hypertension: a cross-sectional study in a Swedish population
Background: The aim of this study was to investigate the association of sex hormone-binding globulin (SHBG) and hypertension in a Swedish population. Methods: The study is based on a random sample of a Swedish population of men and women aged 30-74 years (n=2,816). Total testosterone, oestradiol and SHBG were measured in 2,782 participants. Free androgen index was then calculated according to the
Tema bokhistoria i Lychnos. Årsskrift för idé- och lärdomshistoria
Teknikerna att skriva och trycka eller med hjälp av andra grafiska metoder reproducera den mänskliga hjärnans produkter har och har haft en på alla plan genomgripande inverkan på hur samhället och kulturen formats och utvecklats. Att i idéhistorikernas årsbok erbjudas att göra ett temanummer om bokhistoria upplevde vi därför som speciellt roligt och utmanande. Här hade vi en arena där ljuset tradi

Search for displaced vertices arising from decays of new heavy particles in 7 TeV pp collisions at ATLAS
We present the results of a search for new, heavy particles that decay at a significant distance from their production point into a final state containing charged hadrons in association with a high-momentum muon. The search is conducted in a pp-collision data sample with a center-of-mass energy of 7 TeV and an integrated luminosity of 33 pb(-1) collected in 2010 by the ATLAS detector operating at
Corrector-based magnet alignment procedure
A method of realigning the quadrupole magnets in storage rings to achieve minimum dipole corrector strengths is described. The corrector strengths after realignment are mainly determined by Beam Position Monitor offsets relative to the quadrupole magnets they have been calibrated against and the extent to which magnet dipole errors stay constant during the realignment. The accuracy to which quadru
Risk Factors of Tumour Recurrence and Reduced Survival in Rectal Cancer
In Sweden, 2000 patients are diagnosed with rectal cancer annually. In 1995, the Swedish Rectal Cancer Registry (SRCR) was launched to supervise and assure the quality of the management of rectal cancer. Advances in the management of rectal cancer have reduced the local recurrence (LR) rate and improved survival. To improve the outcome further, identification of prognostic and predictive factors i
Alpha-1-antitrypsin deficiency and periodontitis, a pilot study
The aim of this study was to investigate if periodontal parameters and elastase in gingival crevicular fluid (GCF) are different in alpha-1-antitrypsin deficient (AATD) subjects compared to subjects with normal AAT level. Thirty subjects were included, 20 of whom with severe AATD, phenotype PiZZ. Ten AATD subjects suffered from chronic obstructive pulmonary disease (COPD, group 1) and 10 were asym
Optimization, evaluation, and characterization of a hollow fiber supported liquid membrane for sampling and speciation of lead(II) from aqueous solutions
Hollow fiber supported liquid membrane sampling and speciation of lead(II) from aqueous solution using a selective carrier (Kelex 100) is studied. An optimization of different variables affecting permeation performance (chemical conditions of the sampling module - pH, concentration and nature of the acceptor phase, extractant concentration; membrane impregnation form; sampling time; and hollow fib
FTO, Type 2 Diabetes, and Weight Gain Throughout Adult Life A Meta-Analysis of 41,504 Subjects From the Scandinavian HUNT, MDC, and MPP Studies
OBJECTIVE-FTO is the most important polygene identified for obesity. We aimed to investigate whether a variant in FTO affects type 2 diabetes risk entirely through its effect on BMI and how FTO) influences BMI across adult life span. RESEARCH DESIGN AND METHODS-Through regression models, we assessed the relationship between the FTO single nucleotide polymorphisms rs9939609, type 2 diabetes, and BM
Deformed bubble nuclei in the light-mass region
Nuclei with a central region of low nucleonic density, "bubble" nuclei, are studied. In particular, the possibility of bubbles in deformed nuclei is discussed, concentrating on experimentally accessible light nuclei. Utilizing the relativistic mean field (RMF) model we find favorable candidates in the prolately deformed Ne-24 nucleus and the mirror nuclei Si-32 and Ar-32 with oblate shapes.
Evidence for the formation of quasibound states in an asymmetrical quantum point contact
Features below the first conductance plateau in ballistic quantum point contacts (QPCs) are often ascribed to electron interaction and spin effects within the single mode limit. In QPCs with a highly asymmetric geometry, we observe sharp resonance peaks when the point contacts are gated to the single mode regime, and surprisingly, under certain gating conditions, a complete destruction of the 2e(2
Exploring the environmental impacts of olive packaging solutions for the European food market
Reduction of packaging waste has been a European target for more than 40 years. However, packaging is indispensable for protecting what it carries. In this study, an analysis of the European regulations on packaging and of their resulting effect on recycling performance was performed by means of a literature survey and the national results published in the European Database, Eurostat. Based on the
